Just to clarify, you mean LEDs, AVRs, ICs, etc are NOT allowed, correct?

This is a terribly exciting, and terribly frustrating. As I have never had a GF or any laser cutter. I don’t fully understand its capacities or limitations. I do on paper, but it’s not the same.
I definitely feel slightly handicapped in this.

Indeed, this is why anything I submit will come with a giant disclaimer of “concept only, vectors need to be perfected with real laser and real materials”.
CNC and 3d printing proves this out. I am getting better but things almost always need tweaking.

I guess I’ll be the one to pop this cherry:
I’ve actually got a little material left. I could maybe make some little wooden livestock to throw
(Oh, and for an idea of scale and explanation, the round central pivot is sized for a standard round pencil.)

No promises, but if you include an SVG and materials list with your submission… well, who knows what would happen.

IC = integrated circuit. AVR is a type of computer chip architecture. Basically electronics.

This is FANTASTIC!

Oh shoot, now I’m going to need to figure out how to actually convert things into usable formats.
I think this did it… maybe? Help! @smcgathyfay! I need an adult!
and I’ll see about drawing up some livestock ammo for it.
ETA: Oh, and it’s drawn assuming 1/4" stock. I was imagining wood, but I suppose it doesn’t make much difference. Clear acrylic? It’d look like Wonder Woman got a siege engine from the same people who built her jet.
ETA2: Updated a mismeasured part on the SVG based off of @smcgathyfay’s suggestions, but did not change for the kerf, yet.

That downloaded fine into CorelDraw and inkscape. Just had to ungroup and remove the material outline. I think you’re good to go.

Yay! Now we just have to hope GFHQ isn’t reduced to rubble by tiny trebuchets.

Ok one thing I did notice is that the slots and tabs seem to be the same size. This doesn’t account for kerf. It’s the difference of tight fit/no glue or loose fit/with glue.
